Computer Vision Based System for Monitoring of Physical Rehabilitation

Technology Overview

Computer vision techniques can be used to measure physical impairment or disability, a problem that affects more than 500 million people worldwide. Currently, their system is focused on people suffering from Parkinson's disease, where the technology is proving to be of great utility in both mechanistic research and clinical trials.

We seek to extend the application of our technology to the huge unmet needs present in physical rehabilitation, to build a product that will provide feedback to patients on their objective performance and progress. Evidence suggests that feedback can help patients, such as stroke patients, to recover faster and return to higher level of functional performance than would otherwise be the case.

However, a convenient and user-friendly product need to be created, which is useful and liked by both physiotherapists and patients. Thus, we are seeking a Singapore company working in the area of physical rehabilitation in orthopaedics and stroke with whom to develop such a tool.

Technology Features & Specifications

Our platform, Kelvin, is cloud based and can be accessed using any camera-enabled smart device, such as a smartphone or tablet. Video clips captured during assessment are analysed, using a branch of computer vision known as pose estimation. This allows objective features of the movements to be extracted automatically, providing rapid and objective feedback on the quality of the movement. Once trained, because the clinical expertise is contained in the parameters of an algorithm, even an unskilled operator can use Kelvin.

Potential Applications

Kelvin can be used anywhere where movement assessment is of utility. It therefore has applications in clinical trials for conditions such as Parkinson's disease, stroke and multiple sclerosis (MS). However, it is also useful for setting insurance premiums or determining care requirements, for example. We believe that these systems can also improve outcomes in physical rehabilitation by providing rapid and objective feedback to patients. Finally, it is likely that this technology could provide a vital component in systems that require functional feedback, such as deep brain stimulators and other forms of machine-brain interfacing equipment.

Market Trends and Opportunities

Over 500 million people worldwide suffer from some form of physical impairment or disability. Neurological disease, is responsible for a large proportion of this disease burden, and is itself the largest area of unmet need in the whole of medicine. We estimate the worldwide market in physical assessment today is worth around $50bn per annum. The main attraction of our system is their affordability, flexibility and convenience of use. Other systems (e.g. gait labs or wearables) are as or more accurate, but they are relatively more expensive and inconvenient to use. 

Customer Benefits

For commercial and scientific research - data of a superior quality and quantity.

For rehabilitation patients - objective and rapid feedback on recovery, creating greater engagement and achieving better outcomes.

Currently, state-of-the-art assessment for both applications above is performed by skilled human assessors which are generally costly and assessment could potentially be subjective.
